Halo settings: surround round centres with smaller accent diamonds, amplifying visual presence. Halo engagement rings create the appearance of larger centre stones within modest budgets.
French pavé settings: feature continuous diamond sparkle along the band. French pave engagement rings use small metal beads to secure diamonds whilst minimising visible metal between stones.
Three-stone settings: flank round centres with complementary side diamonds. Three stone engagement rings accommodate matching round side stones for symmetrical appeal.
